Today one if our members has noticed one if the topics they created has a massive reduction in the number if posts and views, yet no one had deleted anything (checked the admin and moderator actions) auto-pruning is switched off too. I have tried resyncing the forum but it has not changed anything.

Any advice?

Edit: What seems to have happened is the topic has been split and locked automatically one 990 posts where reached - can you confirm this is normal behavior of the forum?
